Investigation of regularities of synthesis, composition, structure and properties of epoxy meth acrylate oligoesters

The synthesis of oligoetherepoxymethacrylates has been carried out by esterifi cation of trialkyl triepoxide with methacrylic acid. The infl uence of esterifi cation conditions on the composition and yield of reaction products has been studied. It is shown that by varying the reaction conditions, the process can be directed towards preferential obtaining mono-, di- and trimethacrylic oligoesters. Synthesized oligoesterepoxymethacrylates have been used as a modifi er of epoxy resin. Self-extinguishing compositions were obtained on the basis of ED-20 epoxy resin and synthesized oligoesterepoxymethacrylates. The materials obtained by curing these compositions with amine and anhydride hardeners are characterized by improved physico-mechanical, adhesive and thermophysical properties.
